Ectopic osteogenesis and hematopoiesis after implantantion of bone marrow cells seeded on HAP/PLLA scaffold / Ektopična osteogeneza i hematopoeza iz implantiranih ćelija koštane srži na matrici od biokompozita HAP/PLLA
(Belgrade : Association of the Chemical Engineers of Serbia, 2009)
Bone tissue reconstruction and reparation is a big challenge in medicine. Biocomposite materials based on hidroxyapatite are widely used in reparation of bone defects. Adult bone marrow-derived stem cells may be considered ...
Correlation between isothermal expansion and functional properties change of the Fe81B13Si4C2 amorphous alloy
(Belgrade : International Institute for the Science of Sintering, 2009)
The structural changes effect on functional properties of ribbon shaped samples of the Fe81B13Si4C2 amorphous alloy during annealing process was investigated in this paper. Differential scanning calorimetry method has shown ...
Hydrothermal synthesis of nanosized pure and cobalt-exchanged hydroxyapatite
(Philadelphia : Taylor & Francis, 2009)
Pure and cobalt-exchanged hydroxyapatite (HAp and CoHAp) powders were synthesized by hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, particle size analysis, inductively coupled plasma (ICP) emission ...
Treatment of osteoporosis alveolar bone with cobalt substituted hydroxyapatite nanoparticles
(Belgrade : Institute of Technical Sciences of SASA, 2009)
In this study nanocomposite was used for reconstruction of alveolar bone defect of mandible. Specifically, the main interest for the use of magnetic nanoparticles in biomedical applications is that an inhomogeneous external ...
Controllable synthesis of horseradish peroxidase loaded poly(D,L-lactide) nanospheres
(American Scientific Publishers, 2009)
In this work, horseradish peroxidase (HRP), a model protein, was encapsulated by the precipitation method with additional step of homogenization, using polymer poly(D,L-lactide) (PDLLA). The purpose of this study was to ...
Poly(lactide-co-glycolide)-based micro and nanoparticles for the controlled drug delivery of vitamins
(Bentham Science Publishers, 2009)
Controlled drug delivery systems and polymeric carriers have undergone significant development in recent years. Polymers like polylactides (PLA), polyglycolides (PGA), poly(lactide-co-glycolides) (PLGA), are approved by ...
The master sintering curves for BaTi0.975Sn0.025O3/BaTi0.85S n0.15O3 functionally graded materials
(Elsevier, 2009)
The most important aim in the design and processing of functionally graded materials (FGMs) is to produce devices free from any deformation. Smart choices of different combination of graded layers, as well as the heating ...
Influence of different degradation medium on release of ascorbic acid from poly(D,L-lactide-co-glycolide) nano- and microspheres
(Springer, 2009)
The major goals of the present study were to examine the effects of the type of release medium on the resulting drug release kinetics and to get further insight into the underlying drug release mechanisms. Spherical micro ...
Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Belgrade : International Institute for the Science of Sintering, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...
Isothermal sintering of BZT ceramics
(Kiev, 2009)
Starting mixtures of BaCO3 •ZnO and Ti02 were mechanically activated for 0,5, 10,20.40 and 80 minutes in a planetary ball mill. The powders obtained were sintered isothermally to temperatures between 1000 and 1300 °C. The ...
